Which animals have evolved from reptiles?

Cleidoic eggs are an adaptation for which of the following?

Which of the following are the wrong statements?
$I.$ Organs which are different in basic structure and origin but perform similar functions are called analogous organs.
$II.$ Organs with different basic structure and origin but perform similar functions are called homologous organs.
$III.$ Homologous organs lead to convergent evolution.
$IV.$ Analogous organs lead to divergent evolution.
The correct combination is:

Match the factors of modern synthetic theory/speciation in Column $I$ with the examples in Column $II$ and select the correct option.

Column $I$	Column $II$
$A$. Natural selection	$I$. Darwin's finches
$B$. Geographical isolation	$II$. Mule
$C$. Hybrid sterility	$III$. Cichlid fishes in Lake Victoria
$D$. Sympatric speciation	$IV$. Biston carbonaria

The number and kinds of organisms are not constant. How do you explain this statement?
